By Joe Cash and Ryan Woo BEIJING (Reuters) -Authorities moved more than 45,000 people in earthquake-hit Tibet to shelters in a massive rescue operation near the foot of the Himalayas, as they wound down the search in a high-altitude environment where the odds of survival were always slim.

More than 14,000 rescue workers have arrived in Tibet to continue the search for survivors after a strong earthquake killed at least 126 people in a remote part of western China.
